For more than a month I'm having a crash problem with the kernel 5.11. It boots up, but when loadaded the display manager (tried SDDM and GDM), the system freezes. It occurs in a Dell Inspiron laptop with AMD GPU Radeon R7. Well, I finally found a solution in the Bugzilla of kernel [https://bugzilla.kernel.org/show_bug.cgi?id=212133]. The solution is add the 'modprobe.blacklist=amdgpu 3' parameter to the GRUB kernel line. It works! The only problem is having to start the graphical server manually. I opened this thread to make developers aware of the problem, if they are not already. I am hopeful for a better and definitive solution soon.
[UPDATE] It works without the '3' in the parameter. The graphics server starts normally. Therefore, 'modprobe.blacklist=amdgpu' is enough to solve the problem.

Hi, I suggest to open bug in opensuse bugzilla and assign it to kernel. YaST do not plan to add specific workarounds for specific kernels in installation. BTW blacklisting amdgpu module is not solution, just workaround to use different driver. Josef
